1. EC-135 Overview: Why This Helicopter Stands Out
The EC-135 RC helicopter is a 1:8 scale model of the iconic Eurocopter EC135, widely used for emergency medical services and law enforcement worldwide. Flywing's RTF (ready-to-fly) version brings this professional helicopter to the RC hobby market with impressive attention to detail.
What makes the EC-135 special:
✅ GPS stabilization - ACE system provides auto-hover and position hold
✅ RTF package - Everything included except batteries
✅ Scale accuracy - Authentic fuselage design and rotor system
✅ Beginner-friendly - Multiple flight modes from stable to agile
✅ 2026 update - New navigation lights at the same price point
The EC-135 sits in the 450L size category, making it ideal for both indoor practice and outdoor flying. Its brushless motor system delivers reliable power while the ACE controller handles stabilization automatically.

3. ACE GPS Stabilization System Explained
The ACE flight control system is what sets the EC-135 apart from basic RC helicopters. Here's how it works:
GPS Features:
🛰️ Position Hold (GPS Lock)
- Helicopter maintains exact position in the air
- Automatically compensates for wind drift
- Perfect for beginners learning to hover
🎯 Auto-Hover Mode
- Release the sticks, helicopter stays in place
- Reduces pilot workload significantly
- Ideal for taking photos or just enjoying the view
🏠 Return-to-Home (RTH)
- One-button return to takeoff point
- Activates automatically if signal is lost
- Safety feature for outdoor flying
Flight Modes:
- Beginner Mode - Maximum GPS stabilization, limited speed
- Sport Mode - Balanced stability and agility
- Advanced Mode - Full manual control for experienced pilots
The ACE controller uses a combination of GPS stabilization, gyroscope sensors, and accelerometers to maintain stable flight. This makes the EC-135 scale model helicopter much easier to fly than traditional flybarless systems.
